How to Use Pepakura Designer

1. Make 3D data

Pepakura Designer does not have features required to design 3D data.

3D data of the model you want to create has to be prepared before using Pepakura Designer.

Pepakura Designer supports common 3DCG file formats, including OBJ, 3DS, and STL. You can use your favorite 3DCG software.

A recommended 3DCG software is Metasequoia. You can use it for 3D model design at no charge. Pepakura Designer reads Metasequoia file with high compatibility.
